There is no set price for a kish as only two or three have sold publicly in the past 2 and a half years. Neither of those went above $500, if I'm not mistaken. An APL Unsaver that was also in great condition (better than this one) went for $1975 recently. Obviously that price is an extreme, and the market has changed drastically in recent times, but the point is it could very well be a perfectly good deal in terms of monetary value.
